Effects of ACTH on corticosteroid and progesterone levels in female baboons depending on the phase of the menstrual cycle
To study the effect of ACTH on the endocrine function of steroid producing glands depending on the level of sex hormones in the body, a comparative study of the dynamics of steroid hormones in the follicular and luteal phases of the menstrual cycle in response to a standard does of ACTH was undertaken in experiments on hamadryad baboons. Concentrations of corticosterone, 11-deoxycortisol, and progesterone were determined in duplicate samples of plasma by radioimmunoassay. It is shown that the sensitivity of the adrenals to a single injection of ACTH is independent of the phase of the menstrual cycle and the inhibitory effects of ACTH on progesterone secretion is exhibited only in the presence of an actively functioning corpus luteus of the ovary.
